Gluing Metal to Wood
While it is possible to glue wood and metal together, it can be quite tricky to do. The problem lies in that the two surfaces are different in density and porosity, resulting in the wood being able to expand and contract a lot more than the metal. As a result, achieving a secure bond is hard.
Attempting to glue anything to metal can be difficult, so it is important that you select the right adhesive to be able to glue metal and wood correctly. When selecting your glue, you will need to consult the label and manufacturer’s instructions in detail. It might seem hard to create a bond between metal and wood, but if you use the right glue, you will be able to create a strong bond that lasts. When selecting an adhesive, you will need to take the following aspects into consideration:
- Tensile strength

When it has set completely, you will have a long-lasting, flexible, and durable bond with a very high tensile strength.
You will not have to clamp the pieces before setting and the glue will dry clear. The glue will not run or drip, either, thanks to its gel formulation, which makes it perfect for use on vertical surfaces, porous surfaces, as well as acting as a filler for small gaps.
You will receive this glue in a side-squeeze container, which offers you extreme control, allowing for pinpointed accuracy and air-tight storage. You can grip the container comfortably and then dispense the perfect amount of adhesive without making a mess. It also comes with a screw-on cap that is self-piercing, which ensures that the nozzle will not become clogged up and that the adhesive will remain fresh.
Premium Option for Gluing Metal to Wood: GORILLA Two-Part Epoxy Syringe
In terms of a reactive adhesive epoxy adhesive, this product by Gorilla is thought to be the strongest. This product is made up of two parts that you will be required to combine before applying the glue. The epoxy comes in a syringe that has two separate barrels, one holding the hardener and the other the resin. This ensures that the two substances are kept separate and will not begin to harden until they are combined. The syringe is simple to use and, once you have combined the two parts and the epoxy has hardened, you will have a strong bond that is highly durable.
This epoxy can be used for household and automotive repairs and is resistant to solvents and water once it has hardened. The epoxy dries completely within just six minutes, which means you have plenty of time to position your pieces correctly. Once dried, it can withstand hot or cold weather conditions.

This product is very popular and is thought to be the best option when you are looking to attach metal to wood. If you have permanent and fast gap fillings that need to be addressed, this epoxy is excellent and is versatile for application on several surfaces. When applying it, you ideally want to be working in temperatures between 50 and 100 degrees Fahrenheit (10 to 37.8 degrees Celsius), it is ideal for use outdoors but can also be used inside.

Instructions on How to Attach Metal to Wood with Glue
We will assist you in how to attach your metal to the wood. Before you can begin applying the glue, you need to ensure that the product you have selected can bond metal to wood. To double-check, consult the product’s label and study it in detail, keeping in mind that not all adhesives can bond metal to wood. All the above-mentioned products can be used to bond metal to wood, ceramics, plastics, as well as an assortment of other materials.
- Workspace: You will need to ensure that your workspace is clean and dry, and that you have assembled all the equipment you will require so that it is nearby and within reach.
- Wood: The wood’s surface needs to be cleaned of all oil, paint, dust, or grease, and it needs to be completely dry. The areas you plan on applying the glue should be taped off.
- Metal: Likewise, the metal’s surface also needs to be clean of all rust, dust, paint, or oil. Next, using 120-grit sandpaper, sand the metal surface to roughen it up slightly. This will ensure that the epoxy grabs onto the surface accordingly.
Depending on whether you are using epoxy glue or superglue, the application process will differ slightly. We have provided a guide for either type of product’s application.
- Gently squeeze the sides of the glue container.
- To just one of the surfaces, apply a small portion of the adhesive.
- Join the wood and metal and grip them together for roughly one minute.
- Allow roughly five minutes for the newly glued surfaces to stand. This will ensure that you have created a secure bond.
- Using a ratio of 1:1, combine the hardener and resin onto a dry, disposable, clean container or surface.
- Within five minutes, apply the adhesive to the surface.
- Join the wood and metal and, if necessary, clamp the items together.
- It will dry in 30 minutes and will take a day to cure completely.
It is possible to bond metal to wood as long as you are using the correct product. It is also imperative that all surfaces are completely clean and dry before any form of adhesives are applied so as to ensure a strong and successful bond. Through using the correct product, as recommended in this article, you can add a whole new element to your crafting, as you will be able to successfully join wooden and metal surfaces.
Frequently Asked Questions
How Do I Remove Excess Glue?
You can use acetone to remove any residue, but ensure that you do so before the adhesive goes hard and cures. If the adhesive has already cured, the only way to get it off is by cutting it away or sanding or scraping it off.
Will Ordinary Wood Glue Work in Gluing Wood to Metal?
We do not recommend this, as ordinary wood glue has not been formulated for this purpose and has been designed to specifically work on porous materials. As metal is not porous, the bond will not be effective.
Is Epoxy Adhesive Conductive?
An epoxy adhesive does not conduct electricity when it hardens.
How Does One Bond Metal to Wood?
You need to start by ensuring that both surfaces are completely clean and dry. Following the instructions of the product, apply the adhesive and allow the glue to completely set. You must follow the manufacturer’s instructions.
Can You Use Superglue to Bond Metal to Wood?
The superglue will dry quickly, so you will need to work fast. Superglue can be used to fix an assortment of items as it is a bonding agent.
Does Superglue Work on All Materials?
No, superglue does not work on foam, polypropylene, polyethylene, or plastic, as the glue will dissolve the material due to the chemicals in it.
What Is the Best Glue for Metal to Wood?
Most DIY-ers and craft enthusiasts say superglue is the best option for these sorts of jobs. When you are dealing with larger jobs or working on a professional level, then epoxy is preferred as it offers a bond that can be worked on once it has been set.
Why Won’t My Superglue Bond?
If your surfaces are not completely dry and clean, we suggest using a little acetone to remove any paint, dirt, or oil. Certain woods contain tannic acids that stop the curing process, so it is important to remove any oily substances from the wood using some activator.
